Connecting Low Voltage Inputs
Connecting Low Voltage Inputs
The LiteKeeper 8® logic board can support up to 64 switch
inputs. Of these 64 inputs, 8 of them may be dry contact
closure inputs that are connected to the terminal blocks on
the left side of the LiteKeeper® Logic Board. Digital switch
inputs may also be used on the LiteKeeper®. If no contact
input type switches are being used, the full 64 switch inputs
may consist of digital switches. If a combination of contact
input switches and digital switches are being used, the
combined total cannot exceed 64 inputs.
Regardless of input type used, it is recommended that all
input wiring be done prior to applying power to the logic
board. Please verify that there are no shorts to AC Ground
prior to connection of input devices.
Regardless of input type, the following notes apply.
1. All low voltage wiring is Class 2 wiring.
2. All low voltage wiring must enter the cabinet into the
low voltage section of the enclosure. Low Voltage wiring
can be brought into the enclosure from the left side of
the enclosure. Failure to separate high voltage from low
voltage wiring may cause interference with logic board
function.
3. All low voltage wiring must be run in separate conduit
from line-voltage wiring.
4. Test all low voltage wiring for shorts to AC ground
before connection to the relay panel.
5. When powering peripheral devices such as motion
sensors and photocells from the LiteKeeper® panel,
there may be a limitation on the number of sensors that
can be supported. This is also true if digital switches are
used with the system. See the recommendations below
or contact Cooper Lighting Solutions' for further
information.
6. It is recommended that power be removed from the
logic board when doing initial switch input wiring.
Contact Input Switch Wiring
This section describes the wiring for dry contact closure
devices. There are eight switch input wiring terminals on the
left side of the LiteKeeper-8® to allow for wiring of the dry
contact closure devices.
1.
Use 18AWG twisted, unshielded wire for all low voltage
dry contact closure device wiring.
2.
Maximum length for dry contact closure device wiring
is 1000 feet.
3.
Please see wiring detail below for details on connections
of different devices to the LiteKeeper 8® system.

Contact Input Photosensor and Greengate Sensor
Notes
It is possible to use a contact input photosensor and
Greengate motion sensors in conjunction with the lighting
control system. The LiteKeeper 8® is capable of powering a
number of these devices. Please refer to the chart below for
details on how many devices the transformer can support.

Please contact technical support if it is necessary to power
additional sensors beyond the numbers listed above. These
figures do not account for additional devices such as digital
switches being used. If using a combination of devices,
please contact technical support for exact limits on how the
number of devices the logic panel can power.
